Ellen Degeneres said President Donald Trump was persona non grata on her show during a chat with longtime "Today" co-anchor Matt Lauer on Thursday.

"Because I'm not gonna change his mind," she said. "He's against everything that I stand for."

Lauer also shares his feelings toward President Donald Trump's war on the media, and tells DeGeneres he believes it's going to die down. Later, Lauer gets schooled by presidential expert Macey Hensley in two rounds of presidential trivia.

In addition to talking presidential politics they both celebrated a 20th anniversary this year — Lauer for 20 years hosting "Today" and DeGeneres for 20 years since coming out on national television.
